Pyreverse

pyreverse is a powerful tool that creates UML diagrams from your Python code. It helps you visualize:

• Package dependencies and structure

• Class hierarchies and relationships

• Method and attribute organization

For a detailed external guide explaining the meaning of each arrow and relationship, please see this UML Class Diagram Arrows Guide.

Output Formats

pyreverse supports multiple output formats:

• Native formats:

  • .dot/.gv (Graphviz)

  • .puml/.plantuml (PlantUML)

  • .mmd/.html (MermaidJS)

• Additional formats (requires Graphviz installation):

  • All Graphviz output formats (PNG, SVG, PDF, etc.)

  • pyreverse first generates a temporary .gv file, which is then fed to Graphviz to generate the final image
